No -- it is just as I wrote it.
If I switch from high to medium gain, and select steps around 3 PM area, the steps are slightly smaller, and allow more precise control, if I have to go this route, which I never do, but I could if I needed to.
BOTTOM LINE:
The steps all the way around are pretty close, anyway, and really isn't a source of concern for me. If I switch between high and medium gain, I get even more precise control.
Like I said, I've read several times that many designs are made to have variable differences in the steps. I dn't remember if it applied specifically to HR controls.
Why don't you ask HR, if you need to know for sure whether there are variable steps used? And let us know here.
